These types of LEDs are becoming more used in automotive lighting. You will commonly see these used in red for brake lights and even amber for parking lights. White is also used with these types of LEDs. These types of LEDS use a focusing lens to give out a more piercing color definition but it also limits the brightness and wide output compared to SMDs. These LEDs are more seen and used due to their price in respect to performance. Another thing to know is that with LEDs most people overlook the quality of the product. You cannot tell one product from another simply by looking at a photo, there are a lot of copies. Understand there are LED chip manufacturers and housing manufacturers. So, you may see a similar product using the same housing but different LED chip. The only way to tell if you are getting a well made product is through testing. We test every style and type out there that we can get our hands on and always find a plus and minus. This is where we use our research and experience to understand what is the best way to design an automotive LED.
